In this work, we describe the synthesis of epoxidized sunflower oil (ESO) and its incorporation as a bio-plasticizer of PVC by the partial substitution of bis (2-ethylhexyl) phthalate (DEHP). The formulations are based on PVC and a plasticizer binary system (ESO/DEHP) varying from (00/60) Phr to (30/30) Phr. The epoxidation of the sunflower oil gives an oxyrane oxygen (O.O) in order of 6.2%. The optical properties of the so-obtained PVC formulations (ESO) are experimentally characterized by infrared Fourier transformer (FTIR) and Ultraviolet Visible (UV-Visible). The mechanical properties are determined using the tensile strength, Hardness shore D and A. The results show that after a partial substitution of DEHP by ESO (up to 20 Phr), the films maintaining the suppleness of the PVC and without reaching a stage of thermal degradation.

在这项工作中，我们描述了环氧化向日葵油（ESO）的合成及其通过邻苯二甲酸双（2-乙基己基）酯（DEHP）的部分取代而作为PVC的生物增塑剂并入的过程。该配方基于PVC和增塑剂二元体系（ESO / DEHP），范围从（00/60）Phr到（30/30）Phr。葵花籽油的环氧化产生约6.2％的氧代氧（OO）。如此获得的PVC配方（ESO）的光学特性通过红外傅立叶变换器（FTIR）和紫外可见光（UV-Visible）进行了实验表征。机械性能由拉伸强度，肖氏硬度D和A确定。结果表明，用ESO部分取代DEHP（最高20 Phr）后，薄膜保持了PVC的柔软性，并且没有达到热阶段。降解。
